This disclosure is directed to systems, methods, apparatuses, and techniques that utilize enhanced gesture-based input mechanisms to facilitate rapid creation and editing of digital music compositions. These technologies can be specially designed and configured to optimize creation, editing, and/or sharing of digital music compositions on mobile electronic devices that include capacitive sensing mechanisms. The technologies include multi-gesture functionalities that enable users to view and access various notation customization features in a compact space of a mobile device display. Additionally, the technologies encompass improved data storage models that enable underlying notation data to be accessed in multiple operational modes, and permit frequencies or pitches of notations to be accurately generated and incorporated into audio signals.

A device for automatically generating a real time accompaniment of input music data includes a music input that receives music data. A music analyzer analyzes received music data to obtain a music data description including one or more characteristics of the analyzed music data. A query generator generates a query to a music database including music patterns and associated metadata including one or more characteristics of the music patterns, the query being generated from the music data description and from an accompaniment description describing preferences of the real time accompaniment and/or music rules describing general rules of music. A query interface queries the music database using a generated query and receives a music pattern selected from the music database by use of the query. A music output outputs the received music pattern.

Embodiments described herein relate to techniques of coordinating sensory event timelines of multiple devices. The devices may use the sensory even timelines to output sensory events such as audio segments. The devices may take turns determining the sensory events to be output by the devices using their sensory event timelines. The techniques coordinate transitions of the devices between a first mode in which a device is allowed to determine sensory events to be output and a second mode in which a device outputs sensory events determined by another device.

The present disclosure is directed at methods, apparatus and systems for implementing an improvised guitar playing feature on a rhythm-action game. The improvised guitar playing feature allows players to manipulate a guitar controller to produce a pleasing, musical-sounding improvised play even if the players have little experience or skill at improvising music. This feature uses quantized 8.sup.th and 16.sup.th note musical phrases, or “licks”, strung together to form authentic, melodic, and rhythmically musical and impressive guitar lines, regardless of the player's ability. The improvised guitar playing feature can also display cues directing the player to improvise in a certain manner, while still providing players a degree of musical freedom in selecting how to play. In some embodiments, the present disclosure is also directed at scoring mechanisms for evaluating improvised guitar play.

An electronic musical instrument includes a progression speed changing unit that changes a progression of transport using a predetermined formula such that a total time required for the transport to pass through a specific step section of musical piece data is not changed; a parameter setting unit that sets a parameter for the predetermined formula; and a musical phrase generator that generates a musical phrase by assigning the parameter set by the parameter setting unit to the predetermined formula based on the progression of the transport changed by the progression speed changing unit.

A method and apparatus for the creation and playback of music and/or sound, so that sound sequences are generated that vary from one playback to another playback. In one embodiment, during composition creation, artist(s) may define how the composition may vary from playback to playback using visually interactive display(s). The artist's definition may be embedded into a composition dataset. During playback, a composition data set may be processed by a playback device and/or a playback program, so that each time the composition is played-back a unique version may be generated. Variability during playback may include: the variable selection of alternative sound segment(s); variable editing of sound segment(s) during playback processing; variable placement of sound segment(s) during playback processing; the spawning of group(s) of alternative sound segments from initiating sound segment(s); and the combining and/or mixing of alternative sound segments in one or more sound channels. MIDI-like variable compositions and the variable use of sound segments comprised of a timed sequence of MIDI-like commands are also disclosed.

Real-time jamming is automatically assisted for musicians. A real-time audio signal is received of played music that is played by at least one person. Beat is tracked of the played music from the real-time audio signal and accordingly a time of a next beat is predicted. At least one of chords; notes; and drum sounds is recognized from the real-time audio signal and repetitions in the played music are accordingly detected. A next development is predicted in the played music, based on the detected repetitions, including at least one of chords; notes; and drum sounds that will be played next, and respective timing based on the predicted time of the next beat. A real-time output is produced based on the predicted next development in the played music.

A method and a device provides a user with the ability to freely improvise or play around with a selection of different chords and be provided with visual guidance assisting the improvisation of melody, while also providing accompaniment consistent with the selection of chords. Sound files consistent with a user selection of a chord and/or a dynamic level are selected from an audio library and played, while the user is given visual cues on a user interface keyboard assisting the user to select notes that are consistent with the chord selected for the accompaniment.
